Evidence-based care for older people with colorectal cancer: a grey area

Colorectal cancer is primarily a disease of ageing. There is evidence that older patients are less likely to receive guideline-recommended treatment than younger patients based on their age alone. However, treatment decision-making for this group can be complex. This thesis presents a series of studies that explore the barriers to evidence-based care of older people with colorectal cancer in New South Wales (NSW), with a focus on the receipt of adjuvant chemotherapy and radiotherapy. Chapter 1 provides an introduction to the role of age in cancer care and outcomes. Chapter 2 examines issues in the measurement of patient-reported outcomes that may affect the care that older patients receive. Chapter 3 establishes current levels of adjuvant therapy use for colorectal cancer in NSW and identifies that patient age alone continues to impact treatment receipt. Surgeon knowledge and views and patient preferences for adjuvant therapy are explored in Chapters 4 and 5. A risk model that could be used by clinicians to assist treatment decision-making is developed in Chapter 6. The final chapter discusses implications of the work for clinical practice and for the future research that is needed to ensure greater understanding and improved outcomes for older people with colorectal cancer

Physical activity for people living with dementia: carer outcomes and side effects from the perspectives of professionals and family carers

Adherence to physical activity is challenging for people living with dementia, and largely dependent on carers' involvement. Carers are likely to support physical activity based on their perceived balance between benefits and potential side effects of such intervention for both patients and themselves. Professionals also have a role in terms of optimising such interventions not only for people with dementia but also their carers.publishe

Photographic protocol for image acquisition in craniofacial microsomia

Craniofacial microsomia (CFM) is a congenital condition associated with orbital, mandibular, ear, nerve, and soft tissue anomalies. We present a standardized, two-dimensional, digital photographic protocol designed to capture the common craniofacial features associated with CFM

Relationship between chronic pain and cognition in cognitively intact older persons and patients with Alzheimer's disease; the need to control for mood

Background: Brain areas that are involved in cognition and mood also play a role in pain processing. Objective: The goal of the present study was to examine the relationship between chronic pain and cognition [executive functions (EF) and memory], while controlling for mood, in cognitively intact older persons and in patients with Alzheimer's disease (AD). Methods: Two groups of subjects participated: 20 older persons without dementia and 19 patients in an early stage of probable AD who suffered from arthrosis/arthritis. Pain intensity and pain affect were assessed by the Colored Analogue Scale for Pain Intensity and for Pain Affect, the Faces Pain Scale (FPS) and the Number of Words Chosen-Affective (NWC-A). Level of depression and anxiety were evaluated by questionnaires. EF and memory were assessed by neuropsychological tests. Results: The results show that significant correlations between specific cognitive functions, pain intensity and pain affect were lacking in the cognitively intact older persons. Cognition, in particular memory, appeared to be related to depressive symptoms. In contrast, a significant positive correlation was observed between EF, pain intensity and pain affect measured by the FPS in the AD group. Conclusions: Although older persons with depression were excluded, in studies on pain and cognition one should control for the presence of depressive symptoms in older persons with and without dementia.

Scientific Validation of Three-Dimensional Stereophotogrammetry Compared to the IGAIS Clinical Scale for Assessing Wrinkles and Scars after Laser Treatment

Measuring outcomes from treatments to the skin is either reliant upon patient’s subjective feedback or scale-based peer assessments. Three-Dimensional stereophotogrammetry intend to accurately quantify skin microtopography before and after treatments. The objective of this study is comparing the accuracy of stereophotogrammetry with a scale-based peer evaluation in assessing topographical changes to skin surface following laser treatment. A 3D stereophotogrammetry system photographed skin surface of 48 patients with facial wrinkles or scars before and three months after laser resurfacing, followed immediately by topical application of vitamin C. The software measured changes in skin roughness, wrinkle depth and scar volume. Images were presented to three observers, each independently scoring cutaneous improvement according to Investigator Global Aesthetic Improvement Scale (IGAIS). As for the results, a trend reflecting skin/scar improvement was reported by 3D SPM measurements and raters. The percentage of topographical change given by the raters matched 3D SPM findings. Agreement was highest when observers analysed 3D images. However, observers overestimated skin improvement in a nontreatment control whilst 3D SPM was precise in detecting absence of intervention. This study confirmed a direct correlation between the IGAIS clinical scale and 3D SPM and confirmed the efficacy and accuracy of the latter when assessing cutaneous microtopography alterations as a response to laser treatment
